Process of making a wet formed cellulosic product and a wet formed cellulosic product
View Patent ↗According to the disclosure, a process of making a wet formed cellulosic product and a wet formed cellulosic product are disclosed. The process includes providing a slurry, forming the slurry into a cellulosic product, dewatering the cellulosic product, drying the cellulosic product, and applying an additive to one or more of the slurry and the cellulosic product. The additive modifies one or more of bulk, charge, potential, cumulative pore volume, surface tension of the cellulosic product.
1. A wet formed cellulosic product, the product comprising;
a cationic surfactant and an additive,
wherein the cationic surfactant is cetyl trimethylammonium bromide ((C 16 H 33 )N(CH 3 ) 3 Br) or the additive is bentonite,
wherein the additive includes one or more of the bentonite; polyacrylamide; montmorrilnites; phylosilicates, anionic additives; polyacrylic acid; polystyrene sulfonate; polymers having an acid selected from the group consisting of sulfonic acid, phosphoric acid, salts of carboxylic acid, salts of phosphoric acid, salts of sulfonic acid, and salts of phosphoric acid; natural polymers; modified natural polymers; synthetic polymers; homopolymers of polyacrylates; homopolymers of polysulfonates; homopolymers of polyphosphates; copolymers of polyacrylates; copolymers of polysulfonates; copolymers of polyphosphates; polyacrylic acid; polymethacrylic acid; polystryrenesulfonic acid; carboxymethylcellulose; guar and xanthan gums; anionic starch; amphoteric starch; copolymers of acrylic acid and acrylamide; silica; calcium carbonate; titanium dioxide; and alumina.
2. The product of claim 1 , wherein the cationic surfactant is cetyl trimethylammonium bromide ((C 16 H 33 )N(CH 3 ) 3 Br).
3. The product of claim 1 , wherein the wet formed cellulosic product is selected from the group consisting of paper and ceiling board.
4. The product of claim 1 , wherein the additive is bentonite.
5. The product of claim 1 , wherein the additive is polyacrylamide.
